Cast nylon modified with laurolactam was prepared by activated anionic copolymerization under the adiabatic condition.Its mechanical properties were studied.
Two series of thermotropic liquid crystalline polyureas were synthesized by the copolymerization of benzidine (or o-tolidine),1,6-hexane diamine and 2,4-toluene diisocyanate.
Self-preparation polymerizable macromolecular surfactant HTP and acrylate monomer were used to prepare the amphiphilic polymer by soap-free microemulsion pentamer copolymerization.
Modified larch tannin was prepared by grafting copolymerization and sulfoalkylation, and successfully used as retanning agent, possessing good water solubility and enhanced penetration rate.
